This is an old question but after years of curiosity and looking I am certain that air conditioned Marinette hulls condensate on the hull sides and run down into the bilge in the summer. My boat never gets enough water to pump it out but the amount is always relative to how much and how long the AC has been running. It is not possible to have a dry bilge forward if you run Air Conditioning and I am no longer concerned by the small amount that collects since I understand the source.
